The terahertz (THz) frequency range has been one of the focal points of intensive research and development worldwide in recent decades. This interest is driven by both scientific and practical reasons. Scientifically, conventional electronic and optical devices are unable to operate at THz frequencies, requiring the development of unconventional devices and systems. Moreover, as electronics and optics converge at THz frequencies, researchers must consider THz devices from both perspectives of electronics and optics/photonics, creating opportunities for deeper understanding of their operational principles.

The doctoral program “FutureTHz” targets exactly this challenge. The program is centered around one of the most promising THz sources: resonant-tunneling-diode (RTD) oscillators. This project systematically investigates the nonlinearities in RTD oscillators, develops accurate analytical and numerical models, validates them experimentally, and explores the use of RTD oscillators in certain application scenarios. A key focus is on in-depth understanding of a technique known as injection locking for achieving precise frequency and phase control of RTD oscillators.

This is a collaboration between TU Wien and University of Applied Sciences Upper Austria, Hagenberg Campus within the doc.funds.connect programme of FWF.
